It's from the movie The Martian in which CNSA helped NASA rescue an astronaut stuck on Mars.
In the movie he plays the head of JPL. I thought that was a nice touch since JPL was founded by Qian Xuesen and so they really do have an ancestral link to CNSA.
In the movie JPL put together a cargo spacecraft to send emergency supplies to Mars in a big rush, and in their hurry they didn't test the payload probably which caused the whole rocket (an Atlas V in the movie) to explode shortly after launch. Upon seeing this CNSA reached out to NASA and offered them to launch their payload on top of a new Mars capable CNSA rocket on the condition that a CNSA astronaut get a seat on their next Martian landing mission to which NASA agreed. The CNSA rocket carrying the (even more rushed) 2nd NASA cargo spacecraft ended up having a successful launch.
